iommu/vt-d: Allocate pasid table in device probe path

[ Upstream commit ec62b442 ]

Whether or not a domain is attached to the device, the pasid table should
always be valid as long as it has been probed. This moves the pasid table
allocation from the domain attaching device path to device probe path and
frees it in the device release path.
